General / Re: fatal error: SFML/Graphics.hpp: No such file or directory

« on: December 04, 2023, 09:57:27 pm »

Hi !

Many thanks for your help !

I had to do the following:
  - include the following line into the CMakeLists.txt file:
add_subdirectory("build/_deps/sfml-src/include/SFML")

  - include the following line into the main.cpp and plots.cpp files:
#include "build/_deps/sfml-src/include/SFML/Graphics.hpp"

  - create a new CMakeLists.txt in the build\_deps\sfml-src\include\SFML subdirectory, this file containing:
target_sources(MySFMLFirstProject PRIVATE
   Graphics.hpp
)

I wouldn' t have guessed this in the first place !
The last point was found thanks to a new error message appearing during CMake configuration asking for a CMakeLists.txt file into this subdirectory, which I created successfully by looking at other examples of CMakeLists.txt files.

Many thanks again !

General / fatal error: SFML/Graphics.hpp: No such file or directory : SOLVED !

« on: December 03, 2023, 08:33:54 pm »

It is now HOURS, that I tried to solve this issue: "fatal error: SFML/Graphics.hpp: No such file or directory"

I am using Visual Studio Code under Windows 11.

I followed the tutorial and I have created the following CMakeLists.txt file

make_minimum_required(VERSION 3.23)
project(MySFMLFirstProject LANGUAGES CXX)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)

include(FetchContent)
FetchContent_Declare(SFML
    GIT_REPOSITORY https://github.com/SFML/SFML.git
    GIT_TAG 2.6.x)
FetchContent_MakeAvailable(SFML)

add_executable(MySFMLFirstProject)
target_sources(MySFMLFirstProject PRIVATE "src/main.cpp" "src/plots.cpp")
target_include_directories(MySFMLFirstProject PRIVATE "${PROJECT_SOURCE_SIR}" )
add_subdirectory("sfml-widgets/src/Gui")
add_subdirectory("sfml-widgets/src/Gui/Layouts")
add_subdirectory("sfml-widgets/src/Gui/Utils")


target_link_libraries(MySFMLFirstProject PRIVATE sfml-graphics ws2_32 wlanapi)
target_compile_features(MySFMLFirstProject PRIVATE cxx_std_17)

if(WIN32)
    add_custom_command(
        TARGET MySFMLFirstProject
        COMMENT "Copy OpenAL DLL"
        PRE_BUILD COMMAND ${CMAKE_COMMAND} -E copy ${SFML_SOURCE_DIR}/extlibs/bin/$<IF:$<EQUAL:${CMAKE_SIZEOF_VOID_P},8>,x64,x86>/openal32.dll $<TARGET_FILE_DIR:MySFMLFirstProject>
        VERBATIM)
endif()

install(TARGETS MySFMLFirstProject)
 

This file is in the following directory C:\Users\Fabrice\Documents\C\firstSFML\my_sfml.
This directory also contains :
    - the "src" directory which contains the 2x source files of my software
    - the "sfml-widgets" directory coming from MIT
    - the "build" directory, which is automatically generated when building the proiect; I guess this is thanks to the FetchContent_Declare(SFML... command in the Cmakelist.txt file

In the main.cpp file (entry point of the software), there is a fatal error on the line
#include <SFML/Graphics.hpp>

BTW, if I remove this line from main.cpp, then the error appears when the build tries to compile some cpp files of the "sfml-widgets" which also have the same line #include  <SFML/Graphics.hpp>

I don' t know what to do!

I tried to directly include the path to the file as #include "build/..../Graphics.hpp" in the main.cpp, but then, as I said, the problem appears when building some modules of the "sfm-widgets" library.

I tried to include the path to the Graphics.hpp into the Cmakelist.txt, but it didn't work, and I guess this is not a clean way of working.

I tried to copy the whole content of the sfml-src directory from the generated build directory as a new directory at the same level as "sfml-widgets" directory. It didn't work, and, again, it doesn' t seem to be a clean way of working.

Could you please help me a I am very frustated ?
